This study describes the synthesis of a novel series of curcumin-inspired compounds via a facile synthetic route. The structures of these derivatives were ascertained using various spectroscopic and analytic techniques. The pharmacological effects of the target analogs were assessed by assaying their inhibition of angiotensin-converting enzyme (ACE). All of the synthesized derivatives exhibited considerable
这项研究描述了通过简便的合成途径合成一系列新的姜黄素类化合物。使用各种光谱学和分析技术确定这些衍生物的结构。通过测定靶类似物对血管紧张素转化酶(ACE)的抑制作用来评估其药理作用。所有合成的衍生物均显示出对ACE的显着抑制,其最大抑制浓度的一半为1.23至120.32μM。在与睾丸ACE(tACE)的对接分析中,最有前途的抑制剂(4j)被有效地容纳在蛋白腔的深裂中,与Glu162,His353和Ala356的原子间紧密接触,与赖诺普利相当。化合物4i,4j,4k,使用Langendorff技术,进一步选择4l和4l来确定其在离体大鼠心脏上的血管舒张活性(心输出量和中风量)。在实验小鼠中测定化合物4j的生物利用度。
